ElMod 4WD is a modern miniature central unit for all vehicles with one drive motor and servo steering.
This central unit is designed for lightly armed military vehicles with a wheel drive or one-motor driven half-tracks.
Description
The universal central unit combines a variety of driving, lighting and sound functions in a compact board. With various expansion options you do not compromise and shape the range of functions according to your needs.
Drive
- 10 A strong, short-circuit and overload protected driver for the drive motor
- Physics engine: realistic driving behavior by simulating mass inertia. The vehicle drives “like a big one”. Acceleration, deceleration, top speed, gear shifting and many other characteristics are simulated.
- All driving parameters are adjustable
Steering
- Steering via steering axe and a servo motor with optional speed-dependent steering traverse
- With optionally available FX Expander: Steering of up to two more individually configurable steering axes via servos with optional speed-dependent steering traverse
Weapons
- With optional FX Expander:
- MG muzzle flash via LED with adjustable firing cadence
- Vertical and horizontal adjustment of the main gun with servo motors
- Shot sound of the main weapon
Lighting
- One or two LEDs can be connected directly to all light channels. No further wiring is necessary.
- All light connections are short circuit proof. The LEDs can not be damaged in case of accidental polarity reversal.
- Dimmable front light that can be switched off via the remote control
- Combined tail light with brake light with separately adjustable brightness
- With optional FX Expander:
- Three additional freely assignable light channels
- Indicator with warning light function
Servo functions
- With optional FX Expander: connect up to two servos for different functions, for example (list not complete):
- vertical and horizontal movement of the main gun
- control of additional steering axis
- Opening and closing of hatches
- Operating windshield wipers or radar
- Max. 2 A continuous current consumption for all servos together
Sound generation and noise
- Support of all ElMod sample sets for extra prototypical sound reproduction
- Integrated sound unit plays several different sounds simultaneously
- Sound types drive
- Multiple starter sounds with distinction between cold and warm start
- Multiple shutdown and start-up sounds, engine sounds for driving with simulated gear changes and distinction between full load, part load, engine brake and mechanical brake.
- Turbocharger whistling
- No steps between engine sounds
- Speed-dependent driving sounds such as chain or chassis squeal
- Optional ambient and environmental noises
- Speed-dependent turret rotation noise with optional distinction between drive without and with motor assistance
- Sound for elevation of the main gun
- Fire from main gun optionally as single shot or continuous fire (e.g. flak)
- Variable sounds for bullet impact with simulation of impact at different distances
- Shooting noise for MG
- Up to 24 individual sounds that can be triggered via the radio system, such as horn, radio announcements, etc.
- Plain text announcement when battery voltage is too low/too high
- Configurable volume level of a noise type (e.g. raising the volume of the MG and lowering the volume of the engine) and configuration of multiple sound parameters
- Adjustment of the volume via an included rotary potentiometer
- Adjustment of the volume via a rotary knob on the remote control
- All included sample sets are stored on a PC/notebook-readable microSD card. They may be changed at runtime via the ElMod app.
- Integrated 10 W digital audio amplifier for connecting an 8 ohm speaker
Control
Analog receiver
- A commercial model remote control system (transmitter and receiver, 40 MHz or 2.4 GHz)
- Connection for up to eight channels
- Two channels for driving
- One channel for optional volume control
- A total of 20 additional functions can be assigned largely freely in addition to the basic functions
- The receiver requires no additional power supply. 5 V BEC are provided
SBus
- Requires the optionally available FX SBus adapter.
- An SBus compatible model remote control system
- Use of up to 16 channels
- Simple wiring. Only one connector with three wires for power and all signals.
- Four channels for basic functions (driving, turret, weapons)
- One channel for optional volume control
- A total of 44 other functions can be distributed over 11 channels in addition to the basic functions
- The receiver does not require an additional power supply. 5 V BEC are provided
Bluetooth / USB
- For wireless connection. Requires the optional Bluetooth adapter.
- Control conveniently on an Android smartphone or tablet or PC or notebook
Configuration
- The free ElMod app provides extensive configuration options on the computer
- USB dongle with a USB cable is included
- Available for Microsoft® Windows® 10, Apple® MacOS® and Android®
- Parameterization, status information and control of all vehicle functions
- Individual vehicle profiles can be created and saved
General
- Operation on NiCd, NiMh or LiPo, LiIon batteries with a voltage between 7.2 V and 11.2 V
- Undervoltage cutoff to protect against deep discharge
- Overvoltage shutdown
- All connectors of socketed type
- Included commercial 15A automotive fuse for drive protection
- Integrated resettable SMD fuse for protection of turret functions
- Compact dimensions (63 mm x 39 mm / 2.5″ x 1.5″)
